Make udev run dahdi_cfg on each device:

* New script: dahdi_cfg_device_args:
   - Just like span_assignments, span_types: may be given
     one or more sysfs devpath's
   - Output the required options for dahdi_cfg. E.g:
       "-S 8 -C 15-28"
   - This may be passed (with any other wanted options)
     to the new dahdi_cfg (which supports '-S' and '-C')

 * Use dahdi_cfg_device_args in handle_device so we configure
   each span from udev.
